Postcode districts in the 01604 area
Approximate. Postcode boundaries and telephone-area boundaries are drawn by different bodies and don't line up exactly — this is reliable at town level and wrong at the margins where a district crosses a boundary.
Calling Northampton from a 01604 number
People answer a local number far more often than an unknown one. Local presence gives a floor a number in the area it's ringing, so a call to Northampton shows a 01604 number rather than one from wherever the business happens to sit. It's an add-on from £49 a month; whether a given code is available depends on what carriers hold at the time, so it's worth asking rather than assuming.
